Attached file reduced testcase (should show 'c') (obsolete) —
I get this on trunk Fennec builds.

I am working on WebGL reftests, and my pages weren't getting their setTimeout or requestAnimationFrame callbacks.

Maybe JS execution ends due to this?

reduced testcase (should show 'c')

This is exhibiting a different bug.
Basically any page gets this error, it seems.

That seems unlikely since JSDOMParser is used only inside of a ChromeWorker: http://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/readerWorker.js#9
If the worker throws and we never post a message back, we might be leaking a <browser> every time this happens, which would be pretty bad. NI'ing myself to look at this when I get a chance.

This will be fixed by bug 1094485, so clearing NI. We should still look into the actual parsing failure, though.
